| Combined Effect (source, load, temperature & time) |
typ.: | 0.15% | |
| max.: | 0.3% | ||
| Time Effect (drift) |
typ.: | 0.05% | 0.5 - 8.5 hours |
| max.: | 0.1% | ||
| Startup Time | max.: | 1 second | Any source/load |

Return to 1% of setting | |
| Ride through | min.: | 21.5 Milliseconds | From loss of source to flag signal |
| Hold up Time | min.: | 5 Milliseconds | After signal flag |
| Overshoot | turn on: | +3% max |
Any source, 5% - 100% load |
| turn off: | none | ||
| Error Sense | 3.3V & 5V: | 0.25V |
Voltage allowance per wire |
| all others: | 0.4V | ||
| Series connection (output floats) |
500V | Maximum voltage off ground | |
| Parallel connection (for redundancy) |
Current shares within 5% of rated load |
5% - 100% load | |
| Selective overvoltage shutdown |
Adjustable 100% - 140% of nominal, factory set to 130% |
Latched, reset by cycling source power off | |
| Current limiting |
Constant Current mode Factory set 110% of IO max |
Optional shutdown mode with 20 second delay | |
| Remote on/off | RC-1 | Normally high | Isolated form C or TTL |
| RC-2: | Normally low | ||
| Overtemperature | Thermostat, auto restart | With hysteresis | |
| (1) | External voltage programming only, otherwise -30% to +10%. -30% to +25% for 48V models |
